NAME

Template::Sandbox::NumberFunctions - Basic number functions library for Template::Sandbox.

SYNOPSIS

  use Template::Sandbox::NumberFunctions qw/:all/;

  # or:

  use Template::Sandbox::NumberFunctions;

  my $template = Template::Sandbox->new(
      library => [ Template::Sandbox::NumberFunctions => qw/ucfirst uc lc/ ],
      );

DESCRIPTION

Library of basic string manipulation functions for easy import into a Template::Sandbox template.

EXPORTABLE TEMPLATE FUNCTIONS

int( number )

Rounds number down to the first integer of lower value as per Perl's int().

round( number )

Rounds number to the nearest integer using mathematical rounding, that being 0.5 and greater being rounded up and everyhing below 0.5 being rounded down.

abs( number )

Return the absolute value of number as per Perl's abs() function.

numeric( number )

Reformat number for pretty display by adding thousands commas. Note that this does not respect locale.

currency( number )

Reformat number for pretty display by adding thousands commas and displaying to two decimal places. Note that this does not respect locale.

accountant_currency( number )

Reformat number for pretty display by adding thousands commas and displaying to two decimal places, additionally negative numbers will be displayed in round brackets rather than with a leading minus-sign. Note that this does not respect locale.

decimal( number, places )

Reformat number for display to places decimal places.

exp( number )
log( number )
pow( number, exponent )
sqrt( number )

Wrappers to corresponding Perl power functions (or ** operator for pow().)

rand( number | array )

Returns either a random number from 0 to number - 1, or if passed an array will return a random element from that array.

srand( number )

Wrapper to srand() Perl function.

min( a, b )
max( a, b )

Returns the min or max value from a or b accordingly.

EXPORTABLE GROUPS

:all

Exports all defined template functions in this library.

:maths

Exports exp, log, pow and sqrt.

:display

Exports numeric, currency, accountant_currency and decimal.

KNOWN ISSUES AND BUGS

There's not really a great many functions in here, the module could be regarded as largely superfluous since you could easily recreate it yourself if you needed it. However it provides a useful example of how to write your own library of template functions.

The pretty display functions don't respect locale and aren't going to do what you want if you're expecting "." as your thousands seperator and "," as your decimal marker.
